* [components][clock_time] Refactor time subsystem around clock_time
Introduce the clock_time core with clock source/event separation, high-resolution scheduling, and boot-time helpers, plus clock_timer adapters for timer peripherals.
Remove legacy ktime/cputime/hwtimer implementations and migrate arch and BSP time paths to the new subsystem while keeping POSIX time integration functional.
Update drivers, Kconfig/SConscript wiring, documentation, and tests; add clock_time overview docs and align naming to clock_boottime/clock_hrtimer/clock_timer.
* [components][clock_time] Use BSP-provided clock timer frequency on riscv64
* [risc-v] Use runtime clock timer frequency for tick and delays
* [bsp] Add clock timer frequency hooks for riscv64 boards

Add Doxygen-style comments for the lwp shared memory public APIs
in components/lwp/lwp_shm.c and the related control structure.
This change is documentation-only and does not modify any runtime
behavior or logic.

This patch introduces a tagged pages allocator to address the existing problems
of page aliasing on specific platforms and the requirement of page coloring.
It implements an affinity-id aware page manager by separating the runtime page
list into two types: a normal single linked-list and a multi-dimensional affinity-list.
Changes:
- Introduced tagged pages allocator and managing algorithm for affinity pages list
- Modified components to support affinity-id list management
- Updated page allocation and freeing functions to handle tagged pages
- Added configuration options for page affinity block size and debugging
- Modified mmap and elf loading to respect affinity settings
- Enhanced page list management to support multi-dimensional affinity-list

This patch introduces a remount feature for the DFS, allowing for the
modification of mount parameters without unmounting the filesystem,
the remount functionality helps modify certain mount flags (like `MS_RDONLY`) without
requiring an unmount, providing more control over mounted filesystems in the system.
The updates is essential for user space init proc to cleanup the runtime
resource, ensuring clean handling of cached data and enhancing system
robustness during power down processing.
Changes:
- Defined new constants for remount flags in `dfs_fs.h`.
- Added the `dfs_remount()` function in `dfs_fs.c` to handle remount operations.
- Introduced a check for unsupported flags and handle error conditions such as invalid paths
or non-directory targets.
- Updated the `dfs_mnt` structure in `dfs_mnt.h` to include a read-only flag (`MNT_RDONLY`).
- The `dfs_remount()` function allows changing the read-only status of a mounted filesystem.
- Added `MNT_LAZY_UMNT` and `MNT_RDONLY` flags to `dfs_mnt` structure.
- Introduced `dfs_mnt_setflags` function for dynamic flag management.
- Updated `dfs_remount` to utilize `dfs_mnt_setflags` for flag setting.
- Enhanced unmount operations with `dfs_mnt_umount_iter` and lazy unmounting.
- Added `dfs_pcache_clean` to handle cache cleanup for read-only mounts.
- Improved error reporting in `dfs_umount` for better user feedback.
- Refactored `sys_mount` to streamline parameter handling and support remounts.
- Introduced `_cp_from_usr_string` helper for user-space string operations.
- Updated internal APIs to ensure consistency in reference count management.

The patch introduces support for system reboot functionality and process teardown,
allowing for a clean shutdown and unmounting of the root filesystem. This is
necessary for ensuring a proper system shutdown process, especially when dealing
with resource cleanup and ensuring that all processes have exited before system
shutdown.
Changes:
- Added `lwp_teardown()` function to handle process cleanup and system teardown.
- Introduced `lwp_pid_wait_for_empty()` to wait for process ID table emptiness
before proceeding with shutdown.
- Updated `dfs_mnt_unref()` to trigger callbacks when unmounting a filesystem.
- Added new reboot types (`RB_AUTOBOOT`, `RB_POWER_OFF`) and implemented their
corresponding actions, including cleanup of processes and unmounting root
filesystem.
- Extended `sys_reboot()` to handle reboot and power off types with appropriate
callbacks for process and filesystem teardown.
- Introduced callback mechanism for root filesystem unmount notifications.

This change introduces the `lwp_runtime.c` component, which provides the
necessary runtime environment for the init process, including boot scripts,
shutdown, and poweroff functionalities. The initialization logic has been
moved from `lwp.c` to this new file, enhancing modularity and flexibility
in handling LWP runtime tasks.
Changes:
- Moved the `lwp_startup` function from `lwp.c` to `lwp_runtime.c` to handle
system initialization and runtime environment setup.
- Added `lwp_teardown` placeholder for system shutdown and cleanup tasks in
the future (though not yet implemented).
- Introduced the `LWP_USING_RUNTIME` configuration option in `Kconfig` to
conditionally enable the runtime environment.
- Updated the `SConscript` to conditionally include `lwp_runtime.c` based on
the `LWP_USING_RUNTIME` configuration.
- Removed the old `lwp_startup` code from `lwp.c`, simplifying the file.

This change introduces the `lwp_signal_kill_all` function, which allows a
signal to be sent to all processes in the system. The function iterates
over all PIDs and sends the specified signal to each process, except those
that are protected from signals. This enhancement provides a convenient way
to broadcast signals across all processes in the system.
Changes:
- Added `lwp_signal_kill_all` function in `lwp_signal.c` to broadcast a
signal to all processes by iterating over all PIDs using the existing
`lwp_pid_for_each` function.
- Introduced a new `kill_all_param` structure to encapsulate the signal
information needed for killing processes.
- Added internal `_kill_each` helper function for sending the signal to each
PID.
- Updated `lwp_signal.h` with the new function prototype for `lwp_signal_kill_all`.
- Modified `sys_kill` in `lwp_syscall.c` to call `lwp_signal_kill_all` when
a process is not specified.

This change introduces the `lwp_pid_for_each` function, which provides a
convenient and thread-safe method for iterating over PIDs with a user-
defined callback. This addition is necessary to support cases where
operations must be performed on each PID in the balanced tree, enhancing
flexibility and modularity for PID management.
Changes:
- Added `lwp_pid_for_each` function in `lwp_pid.c` to allow iteration
over PIDs using a callback function and optional data parameter.
- Defined a new internal `pid_foreach_param` structure to encapsulate
the callback and data for the iteration.
- Added `_before_cb` helper function for executing the callback on each
PID node during AVL traversal.
- Ensured thread safety by acquiring and releasing the PID lock around
the AVL traversal within `lwp_pid_for_each`.
- Updated `lwp_pid.h` with the `lwp_pid_for_each` function prototype and
included `rtthread.h` for necessary types.
